What You Need to Know: Postmenopausal women who in the past 4 years who have undertaken regular physical activity (equivalent to at least 4 hours walking per week) had a lower risk for invasive breast cancer.
The Study: Fournier and colleagues analyzed data from biennial questionnaires completed by 59,308 postmenopausal women who were enrolled in E3N, the French component of the European Prospective Investigation Into Cancer and Nutrition (EPIC) study. The mean duration of follow-up was 8.5 years, during which time 2,155 women were found to have a first primary invasive breast cancer.
Results: Postmenopausal women who in the previous 4 years had undertaken 12 or more MET-h (metabolic equivalent task-hours; roughly equivalent to at least 4 hours walking per week) had a 10% decreased risk of invasive breast cancer compared with women who were less active.
My Take: It is not necessary to engage in vigorous or very frequent exercise; even walking 30 minutes per day seems beneficial. Keep moving, as you may reduce your own risk of cancer, diabetes, high blood pressure, heart attack, stroke, or even dementia! I’m Dr. Michael Hunter.
